The smaller bento box won't fit much. Maybe some tiny gel packets. Does not fit a tube or co2 cannister. I have some turbolite innertubes usually for my backup. But only if I squeeze it in will it fit. Then the question of course is with the long valve length, depending on what wheel your running. I like having an innertube ready to go without having to change the valve, and have a spare 80mm length valve innertube taped behind the saddle.
The bigger bento box looks big, but again it depends on size of gels. I managed to fit four of Torq gels I like and they are 45grs sized. I probably could squeeze in five if I had to. But more likley I will use the downtube bottle for my gel mix and the two bottles as my water/electrolyte option.
I also noticed that the ENve 5.6 wheels need either a 80mm valve innertube, or something like a 37mm valve with the 42mm Enve Valve extension added. If you use a standard 42mm length valve innertube and add the smallest Enve Extension Valve, then the whole valve is just to long and you dont get the benefit of the rubber of the Enve Extensions to protect against valve ratteling in the wheel.
Have now set it up with GP5000 25mm tires, correct valve length and moved my fit over from my previous TT bike, a Felt IA FRD. Final fit is in three weeks, and am adding dura ace own powermeter, as the cannondale srm unit I have is more pain then anything else trying to get installed. Am not bothering with ceramic speed rear derailleur part, as I have broken two already whilst travelling with a bike.

Hi Alexne,
A question about the bento boxes on the top tube.
Looks like there are 2, small and large.
With the smaller one would you fit a tube and a Co2 canister in it?
With the larger one, how many gels do you think you would fit in it?
